Circulation, Volume 148, Issue Suppl_1, Page A16852-A16852, November 6, 2023. Introduction:ECG-monitoring covering several days is recommended by current guidelines to detect atrial fibrillation (AF) and other arrhythmias in stroke patients. In practice, the extent of rhythm monitoring varies. Here, we use data from the 24-hour screening-Holter-ECGs of the ongoing randomized multicenter trial Find-AF 2 to assess the rate of AF and other arrhythmias.Methods and Results:Find-AF 2 (NCT04371055) is a randomized and controlled open-label parallel multicenter trial with central AF adjudication (intervention arm) and blinded endpoint assessment. Patients ≥60 years with recent (≤30 days) ischemic strokes according to the AHA/ASA definition of any etiology are screened for eligibility. All eligible patients receive a 24-hour Holter-ECG prior to randomization. Holter ECG data are analyzed by the core laboratory using dedicated analysis software and following a predefined standard operation procedure. In this analysis, we included all 24-hour Holter-ECGs up to June 1, 2023.We analyzed 3742 24-hour-Holter-ECGs from 51 different centers and found new arrhythmias in 120 patients (3.2%). AF was detected in 61 patients (1.6%) with a median duration of the longest episode of 730 minutes [interquartile range (IQR) 220;1180] (see Figure 1). This led to the initiation of anticoagulation in all 61 patients (100%). In 47 patients (1.3%), pauses >2.5 s (mean 3.1s±0.5s; longest pause 4.8s) or relevant bradycardias

Circulation, Volume 148, Issue Suppl_1, Page A12182-A12182, November 6, 2023. Background:Presence of cardiac and non-cardiac comorbidities is reported to affect success of catheter ablation (CA) of atrial fibrillation (AF), however their predictive value in 1 and 2 year AF free survival is not reported.Research Questions:Which cardiac and non-cardiac comorbidities are most useful in predicting AF free survival after a single CA for paroxysmal and persistent AF.Goals:Create a model to identify potential risk factors that may reduce the long term success of catheter ablation for patients with AF to allow for risk modificationMethods:We included 1435 patients with symptomatic AF undergoing first time CA in 1 of 8 Hospitals of Northwell Health and follow ups for at least 24 months ablation. Baseline echocardiographic and laboratory data were extracted from our common EMR, and clinical outcomes were determined after manual review of the 6, 12 and 24 month visit. Baseline patient characteristics included age, gender, BMI, diagnoses, laboratory and echocardiographic measures used in a stepwise estimation logistic regression model using STATA /IC 16.1.Results:From our patient cohort (age 67.1±10.4, 565 female, 645 persistent), 28% of patients had AF recurrence within the 1st year, and 32.5% within 2 years. Multivariate analysis identified persistent AF as the only independent risk factor for AF recurrence within 12 months (P=.001). For 24-month recurrence the independent predictors were LVEF (p=.014), Diabetes Mellitus (p=.045), cardioversions prior to ablation (DCCV) (p=.001), and pulmonary disease (p=.001). Energy modality was not a significant predictor of AF recurrence. Hypertension (p=.008) was found to be negatively associated with AF recurrence. Our prediction model (Figure 1) for AF recurrence 24 months post-CA produced an ROC curve of 0.8048 and was 77% accurate.Conclusion:The presence of baseline comorbidities implies that such comorbidities, rather than procedural failure, are mostly related with AF recurrence after 1 year.

Circulation, Volume 148, Issue Suppl_1, Page A110-A110, November 6, 2023. Background:Extracorporeal cardiopulmonary resuscitation (ECPR) is an emerging method that improve survival after refractory VF/VT cardiac arrest. Neuron-specific enolase (NSE) and S-100B are used to predict neurological outcome; however, it is unclear the reliability and earliest time point during ECPR.Methods:Single-center, retrospective cohort study included OHCA patients who underwent ECPR at the University of Minnesota between December 2015 and January 2023. NSE and S100B levels were obtained at admission, at 12 and 24h after ROSC in a total of 361 unconscious patients. The primary outcome was poor neurological outcome (defined as CPC 3-5) at hospital discharge. We evaluated the optimal cut-off levels for NSE and S100B by maximizing the Youden index and ROC analyses for poor clinical results. Finally, NSE and S100B at 12h and 24h were added to a multivariable logistic model (age, sex, bystander and witnessed).Results:Of 361 patients, 170 survived to hospital admission. Of these 85% (145/170) survived neurologically favorable. Mean (SD) NSE (ng/mL) values were significantly higher in the CPC 3-5 group at every time point, 52.3 (53) vs 21.1 (12) on admission; 92.8 (92) vs 20 (10) after 12h; 107.1(94.4) vs 21.5 (12.9) after 24h; p

Objective
There are several equations for estimating the glomerular filtration rate (GFR), and each method has its limitations. We compared various estimated GFR (eGFR) equations with 24 hours urine creatinine clearance (24u-CCr).

Design
Sample analysis of randomised controlled trial participants.

Setting and participants
We compared the mean 24u-CCr values measured 2–3 times for 211 patients with eGFR values calculated using the following equations: isotope dilution mass spectrometry-Modification of Diet in Renal Disease (IDMS-MDRD) equation, Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) equation, equations for Koreans (KOR-IDMS-MDRD and KOR-CKD-EPI) and full age spectrum equation.

Outcome measures
Performance of various creatinine-based eGFR equations, including those with Korean coefficients, compared with the results of the 24u-CCr.

Results
IDMS-MDRD showed the best overall correlation with the 24u-CCr (R=0.949, p
